Here is the latest news from Ucore Uranium:

(Vancouver, BC, September 25, 2008) Ucore Uranium Inc. (TSX-V: UCU) is pleased to report that confirmation assays for rare earth elements (REE) and associated metals have now been received from drilling at Bokan Mountain?s I&L zone. Significant results received so far are reported below:

LREO ? light rare earth oxides: La, Ce, Pr, Nd, and Sm in the form LRE₂O₃

HREO ? heavy rare earth oxides: Eu, Gd, Tb, Dy, Ho, Er, Tm Yb, and Lu in the form HRE₂O₃

?Needless to say, we are excited about these results,? said Jim McKenzie, President & CEO of Ucore. ?In addition to our high grade uranium values, the I&L zone is also enriched in rare earth elements and related metals, including yttrium and niobium. What?s particularly exciting is that we?re looking at potentially significant concentrations of highly valuable heavy REE?s, including holmium (Ho), lutetium (Lu), terbium (Tb) and thulium (Tm). These are uncommon at most other North American REE deposits and have valuations ranging from hundreds to several thousand dollars per pound. With escalating worldwide demand for heavy rare earths, Bokan?s HREE potential could well rival the area?s uranium prospects, and certainly adds appreciably to the project?s prospective value.?

Surface sampling has identified several zones with even higher REE values outside of the main uranium-bearing zones. Investigations are being made into the area?s full suite of mineralization, including uranium, REE?s, niobium, beryllium, and zirconium. Samples from the I&L zone have been submitted to a metallurgical facility for mineralogical and recovery testing.

Preliminary metallurgical testing of various REE-mineralized samples from Bokan by the US Bureau of Mines in the 1990?s reported Y, Ce, and La solubilities exceeding 74%. Subsequent loading and stripping recovered over 96% Y with minimal solvent loss.

The term ?rare earth elements? is a trade name for the 15 element lanthanoid series metals plus yttrium characterized by similar physical and chemical properties. Grades are usually reported as calculated rare earth oxides (REO). Demand for rare earth elements is increasing, with supply coming mostly from China. Rare earths are utilized in high technology applications such as petroleum cracking catalysts, glass, computer displays, polishing compounds, alloys, magnets, phosphors, pigments, ceramics, lasers, nuclear energy components, and rechargeable batteries for hybrid vehicles. More details on individual elements are available on the Bokan project page of the company?s web site.

The I&L Zone is one of more than 30 known uranium +/- rare earth element occurrences at Bokan Mountain related to a peralkaline ring dike complex known as the Bokan Intrusive Complex. The Ross Adams Zone, located 450 meters southwest of I&L, produced 1.3 million pounds of U₃O₈ at an average grade of 0.76% between 1957 and 1971. These were among the highest average grades ever recorded by a U.S. based uranium mine. Most of the uranium mineralization in the area is characterized by multiple, steeply dipping, uraniferous quartz-pegmatite veins localized by radial fractures near the margin of the Complex, while most of the REE mineralization is hosted in felsic dikes more distal to the Complex.

NI 43-101 Compliance

Diamond drill core was split on site, with half the core transported by commercial freight carriers to the Activation Laboratories analytical facility in Ancaster, Ontario, Canada. As part of a rigorous QA/QC program, blanks, standards, and duplicates were inserted into the sample train in the field and in the laboratory. Analyses were by a combination of mass spectrometry and X-ray fluorescence. Reported values are length-weighted averages from multiple samples converted from ppm metal reported by the laboratory using a ratio of 1 part light REE = 1.168 parts LRE₂O₃, 1 part heavy REE = 1.146 parts HRE₂O₃, 1 part Y = 1.269 parts Y₂O₃, and 1 part Nb = 1.431 parts Nb₂O₅. Insufficient structural information is available to make a conclusive statement on the relationship between true width and core intercept; however, true width is estimated at 65-80% of apparent width. Harmen Keyser, P.Geol., Ucore?s Vice President of Project Development and a qualified person in accordance with NI 43-101, has reviewed and approved the technical content of this press release. A plan map showing drill hole locations has been posted on Ucore?s web site.
